6. Known Limitations and Workarounds

This section contains information on known limitations and workarounds for the Windows PV drivers.

6.1. Windows Guest Kernel Panic

Windows guests may experience kernel panic when the virtual machine is stopped and started several times. This may also occur if there is intensive I/O. The error in this case is:

(XEN) p2m_pod_demand_populate: Out of populate-on-demand memory!

Workaround: Set the Maximum Memory and the Memory fields to the same value in the Create/Edit Virtual Machine wizard in Oracle VM Manager.

6.2. Found New Hardware Window Displayed During Installation or

Uninstallation

During the installation or uninstallation of the Windows PV drivers, the Found New Hardware window is displayed when the guest restarts.

Workaround: Click Cancel to ignore the message and close the window.

6.3. Guest Cannot Use More Than Eight vCPUs

If you use the Windows PV drivers, the maximum number of virtual CPUs (vCPUs) is eight.

6.4. Crash Dump and Hibernation Fails on Windows Server 2008 R2, Windows

Server 2008, and Windows Vista or Windows 7

To avoid the stop error "0x000000D1" when doing crash dump and hibernation on Windows Server 2008 R2, Windows Server 2008, and Windows Vista or Windows 7, download and install this Microsoft hotfix from: http://support.microsoft.com/kb/2320550/.

6.5. Network Performance Issues

Network performance issues may be experienced with Windows PV drivers Release 2.0.7 on Oracle VM Release 3.0.x. To improve network performance, use Windows PV drivers Release 3.0.1.

Workaround: Disable Large Send Offload support for all network cards available in the Windows virtual machine. Follow these steps to disable Large Send Offload:

1. Open Device Manager.

2. Open Network Adapters, right-click the Oracle VM Virtual Ethernet adapter and select Properties.

3. Select the Advanced tab.

4. Select Large Send Offload in the Property field, select Disabled in the Value field, and then click OK.

The network card will restart automatically and network performance should improve.
